Global 6500 - AFCS Flashcards
When does the AFCS initially engage the yaw damper?
Automatically when a Remove Electronics Unit (REU) and two sources of roll and yaw are available (IRS)
What is the maximum altitude for flight with the yaw damper disengaged?
41,000 ft
What will happen if the YD is disengaged with the AP engaged?
AP will disengage
What is the minimum height at which the autopilot can be engaged?
400 ft AGL
What is the minimum height that the autopilot can be used during a CAT I or CAT II precision approach (ILS)?
Category I or II ILS: 80 ft AGL
What is the minimum height that the autopilot can be used during a non-precision approach with no vertical guidance?
400 ft AGL
What is the minimum height that the autopilot can be used for a non-precision approach with vertical path reference?
160 ft AGL
What is the speed limitation for FLC mode use?
Above .85 M is prohibited
When must both STALL PUSHER switches be on?
For duration of the flight
What are the four purposes of the MSTR DISC pushbutton on the control wheel?
- Disconnects the autopilot,
- Silences a disconnect aural,
- Interrupts pitch trim while held,
- Inhibits the stick pusher while held (non-EASA a/c)
What will cause manual disengagement of the autopilot?
Pressing the AP pushbutton,
Pressing either MSTR DISC pushbutton,
Manual trim activation,
Pressing the YD switch on the FCP,
Physical override of the AP servos (not recommended)
What will cause automatic disengagement of the autopilot?
Unusual attitude,
Stall warning activation,
Activation of windshear avoidance (2-sec delay)
What is the purpose of the touch control steering (TCS) button?
Momentarily overrides the autopilot and sync FPA, speed or VS value
What will happen in the event the master AFCS/AT fails?
Standby AFCS/AT automatically takes over and the FD modes will revert to basic ROLL and FPA
How is the master AFCS identified?
FCP indicator lights adjacent
to the YD and AP buttons
How is the AFCS 1 manually selected to AFCS 2?
Selecting the AFCS 1/2 switch
on the reversion switch panel (RSP)
Does the indicator light on the flight control panel (FCP) indicate that the associated mode is currently active?
No. The pilot must confirm the mode status or operation from the flight mode annunciator (FMA) on the PFD.
How are active/armed flight director and autothrottle modes indicated on the FMA?
Active shows in green, armed shows in white
How does the autopilot engage if no vertical or lateral flight director modes are armed?
Basic ROLL and FPA modes
What is the steepest angle for approaches?
3.5 without AFM supplements
What does the autopilot do in ROLL mode?
Heading hold when the bank is <5’b0, holds the current bank angle if the bank is >5’b0 to a maximum of 30’b0
When is the FMS prohibited as a sole NAV source for instrument approaches?
Localizer-based approaches, VOR approaches, NDB approaches
Note: VOR and NDB approaches require a bearing pointer shown in addition to FMS guidance
What is required for an automatic Nav-to-Nav transfer to occur?
LNAV is the active lateral mode,
the LOC beam is captured,
and APR selected on the guidance panel
